Work Experience
DevOps Engineer
RecVue
- Designed and owns the team's end-to-end Jenkins CI/CD pipelines covering Build, unit test, Docker build, GitHub push, and Kubernetes rolling deployment by reducing release cycle time from days to under 1 hour.
- Implemented environment-based deployment gates in GitHub Actions using environments, required reviewers, and environment secrets for dev / staging / prod promotion workflows.
- Provisioned all RecVue instance infrastructure using Automation — AWS cloudfronts, API gateway, OCI NFS , Kubernetes components, Databricks, and other components
- Deployed and managed Kubernetes applications using Helm charts, streamlining release versioning and rollback across microservices.
- Adopted GitOps practices for Kubernetes deployments, improving deployment consistency and rollback speed
- Integrated Trivy image security scanning into CI pipeline, automatically blocking deployments that contain critical and high vulnerabilities
- Configured Datadog monitors, log pipelines, dashboards, anomaly detection, and alerting integrations for Kubernetes- based microservices, reducing Mean Time to Detect (MTTD) production incidents by 40% and enhancing platform observability.
- Engineered Kubernetes scheduling policies using taints, tolerations, and node affinity to isolate workloads across dedicated application, monitoring, and data-processing nodes, reducing node management complexity by 50% and enhancing cluster reliability.
- Managed AWS Secrets Manager for secure storage and rotation of database credentials and API keys, replacing hardcoded secrets across all microservices.
- Built hands-on proficiency in Azure DevOps (Pipelines, Repos) for a separate microservice
Associate, DevOps and Cloud Engineer
RecVue
- Built and maintained Shell/Bash and Python automation scripts for infrastructure provisioning, deployment activities, and operational tasks.
- Assisted in managing Kubernetes workloads, containerized applications, and Docker image lifecycle across development and testing environments.
- Supported Jenkins CI/CD pipelines for application deployment and release management processes.
- Managed IAM users, groups, roles, and policies following least-privilege principles; conducted quarterly IAM access reviews and remediated over-permissioned roles.
- Assisted in writing initial Terraform modules for EC2, S3, and RDS resources, laying the groundwork for full IaC adoption across the project.
- Managed AWS and OCI cloud resources including compute, networking, storage, IAM, and monitoring services.
- Implemented monitoring dashboards and alerting using Datadog and Grafana to improve system visibility and operational response.
- Collaborated with development, QA, and database teams to troubleshoot production issues and support application releases.
Projects
Jenkins on Kubernetes
- Designed CI/CD pipelines using Jenkins dynamic agents running on Kubernetes.
- Automated container build, deployment, and release workflows.
- Added Slack webhook notifications on deployment success and failure, improving team real-time visibility and reducing post-deployment confusion.
AWS DMS, Databricks & Delta Live Pipelines Project
- Led AWS DMS migration initiatives for enterprise applications, ensuring secure, scalable, and low-downtime data replication across cloud environments.
- Automated operational workflows using Jenkins, Shell scripting, and cloud-native services, improving deployment efficiency and platform reliability.
Datadog Cost Optimization & Observability
- Implemented Datadog observability and cost-optimization strategies through log filtering, container filtering, custom monitors, dashboards,
- Automated alert muting during application deployments, enhancing SLO measurement accuracy, reducing alert fatigue, and improving operational visibility across production environments.
Database Patch Automation
- Automated Oracle database datapatch execution, schema deployments, and release validation using Liquibase, SQL*Plus, Bash scripting, and Jenkins CI/CD pipelines.
- Integrated database change management into CI/CD processes, improving release reliability, deployment consistency, and auditability of database updates.
